Table 2 The size of the genomic stretches from the B. rapa pseudochromosomes showing gene collinearity-based homology with different B. nigra pseudochromosomes. Colored boxes represent the new nomenclature V3 for B. nigra

From: A highly contiguous genome assembly of Brassica nigra (BB) and revised nomenclature for the pseudochromosomes

  1. aV1- BniB LG nomenclature by Lagercrantz et al. [26] based on genetic mapping; V2- BjuB LG nomenclature by Panjabi et al. [11] based on genetic mapping; V3- BniB pseudochromosome nomenclature proposed in this study based on the long-read genome assembly
  2. bExplanation of the numbers - As an example – pseudochromosome A01 of B. rapa has homology with two B genome chromosomes; a region of 15,185,553 bp (51.3% of the total length of A01) with one of the B genome pseudochromosome and a region of 13,228,780 bp (44.7% of the total length of A01) with the other
